Question

Which of the following is not the function of a fuse?

• A. Breaking the circuit
• B. Preventing damage to electrical appliances
• C. Preventing low current to flow through the circuit
• D. Preventing possible fire

Answer 1

The correct option is C Preventing low current to flow through the circuit

Fuse is a safety device that is installed in homes to protect electrical devices from the flow of excessive current.
The fuse prevents the high current to pass through the electrical circuits, prevents possible fires by blowing off and breaking the circuit.
Hence, the fuse does not prevent low current from passing through the circuit.
